Sitka Ambient or Kelvin Aerolite for mid layer

[Laelkhunter]

Just thinking ahead if it gets cold enough, which would you recommend to mid layer under my Sitka Blizzard jacket? Looking at the Ambient or the Kelvin. Both are the same price.

No responses, so I was wondering if anyone has the Ambient that can compare it to other Sitka offerings?

I would probably say the ambient because it is that really breathable fuzzy material. The aerolite seems heavier and less breathable.
